commit 47ac9fee0e3d43b4da33f53b8a2ff590f0d46079

    Addressed issues with EditText causing scroll
   
    EditText methods: bringPointIntoView, and handleFocusGainInternal
    trigger requestChildRectangleOnScreen in ViewPager2's internal
    RecyclerView.
   
    This can cause:
    - unwanted scrolling -- e.g. when typing on some API versions
    - a jump to page 0 -- EditText sometimes reports over -1M px mScrollX
   
    This fix bypasses requestChildRectangleOnScreen calculations taking
    advantage of the fact that PagerSnapHelper constraints valid scroll
    values to a snapped position ones, and as a result, the problem is
    reduced to choosing the correct currentItem.

Fix [1]  for this is planned to be released in 1.0.0-beta04.

beta04 with a fix for this was released today

Btw, as a temporary workaround before a fix is released you can probably copy-paste the FragmentStateAdapter [1] class and patch it locally?

[1] https://android.googlesource.com/platform/frameworks/support/+/androidx-master-dev/viewpager2/src/main/java/androidx/viewpager2/adapter/FragmentStateAdapter.java

In my case the simplest workaround was to add fragment.setMenuItemVisible(false) directly in the createFragment(position) method of my adapters, right before returning the fragment.

    Fix for Fragment menu visibility issue in FSA
   
    The fragment's menu visibility is directly related to the fragment's max
    lifecycle. When the max lifecycle is STARTED, the menu should not be
    visible. When the max lifecycle is RESUMED, the menu should be visible.
   
    This CL fixes the bug where a fragment that is added to the fragment
    manager by FragmentStateAdapter did set the max lifecycle to STARTED,
    but did not set the menu visibility to false.
   
    Relnote: "Fixed `FragmentStateAdapter` issue with initial fragment menu
    visibility when adding a fragment to the `FragmentManager`."

I think this issue relates to https://issuetracker.google.com/issues/147550812 as well and that other issue can be marked as fixed too.
Checked on 1.1.0-alpha01 and can confirm the fix.

Still having issue in alpha, when you slide very fast, icon will disappear for a while!
